Filed: 1985-07-15
Abstract: PURPOSE:To obtain great rotational torque from a coreless type magnet, by providing the stationary side with a cogging generation means to stop the field magnet at a position where it can be self-started. CONSTITUTION:When a permanent magnet is used for a magnetic unit 12 for cogging generation, then the pole N or the pole S for the field magnet 6 of the permanent magnet and the counter magnetic poles for the field magnet 6 are always attracted with each other to stop at the position, and so when current in the specified direction is conducted to an armature coil 8, the magnet is rotated in the specified direction. By this method, the magnet can be self- started even with one positional detection element, and when the magnet is provided with one armature coil 8, rotational torque almost the same as that of brushless motors provided with tow armature coils each can be obtained.

Title: Gas shielded upward arc welding method
Inventor: KUROKAWA TSUYOSHI
IPC: B23K35/368
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To stably form initial beads at overhead position from the rear side of the groove, in which a root gap is provided, by using a flux cored wire that a specific quantity of A1 or Mg is contained in the flux for gas shielded arc welding and performing welding with DC straight polarity. SOLUTION: A flux cored wire for gas shielded arc welding is used such that at least one kind of Al or Mg is contained in the flux so as to satisfy the condition that Al+3Mg is 1-11 wt.% (weight % in the total weight of wire). Both Al and Mg enhance viscosity by reducing oxygen in a molten metal and serve to stabilize an arc with DC straight polarity (arc welding with the wire set as the negative electrode and the object to be welded as the positive electrode). Therefore, this welding direction is suitable for the welding of a job site between a column 1 and a beam 2 and between beams in construction steel frames.

Inventor: KANAI AKIO
IPC: F03B17/04
Filed: 1982-09-13
Abstract: PURPOSE:To provide additional effective power source, by converting upward movement of a floating body in liquid to power. CONSTITUTION:A clutch 28 is engaged, and then a handle 28b is rotated in such a direction as to raise a rack 24. Rotation of a first sprocket 27 is transmitted through a first chain 34 to a reduction gear 31 in a supply drive portion 30. When a bolt 37 is rotated together with rotation of a fourth sprocket 37a, nut members are moved so as to approach to each other. At this time, a pantagraph 32 is displaced so as to be expanded, and thereby to move a push bar 33 provided at a connection portion opposed to a fixed portion 35 to a supply section 10 side, the push bar 33 being inserted into a hole 11 of the supply section 10 to push a floating body 2. In such a circumstance as above, when the rotation of the handle 28b is stopped, the rack 24 falls owing to its tare, and is positioned at a bottom dead center to retain the floating body 2 by a roller at a lower end of the rack 24. Buoyancy is acted on the floating body 2 in the water. Accordingly, the floating body 2 rises along a vertical direction of a water bath 1, while raising the rack 24.

Title: Breaker/trip circuit
Inventor: WATANABE KAZUO
IPC: H01H71/04
Filed: 1992-06-18
Abstract: PURPOSE:To reduce the size of a power source by tripping a breaker without a trip coil by constantly turning a switching device ON in an alarm circuit when the output of a switching part becomes an abnormal level. CONSTITUTION:An alarm circuit 20 is a comparator for comparing two reference values E2, E3 with an output voltage V0 of a switching part 10. An alarm is given by the comparator when the output voltage V0 reaches a level no less than the first reference value E2, or when the output voltage V0 reaches a level no more than the second reference value E3. A switching transistor is constantly turned ON by an alarm signal, and an excess current flows in a primary side circuit. A breaker is tripped by the excess current. Destruction of load is thus prevented.

Title: Fuel injection controller of multi-cylinder internal combustion engine
Inventor: WATANABE HARUO
IPC: F02D41/34
Filed: 1982-09-16
Abstract: PURPOSE:To vary the period of an unsynchronized injection so as to maintain the air fuel ratio of each cylinder more properly by detecting that the timing of acceleration occurs in what interval of adjacent synchronized injections. CONSTITUTION:The time when a throttle valve is opened from the fully closed condition is decided as of acceleration and this information is forced in a step 90. At a step 92, the value T of a free-run timer obtained at that time is stored in RAM. At a step 94, a period DELTATACC from the former synchronized injection time to the unsynchronized injection time is obtained as T-T1. Decision whether DELTATACC is greater than DELTAT/2 or not and whether DELTATACC is smaller than DELTAT-t or not are made at steps 96 and 98, respectively. If YES at both the steps 96 and 98, the subsequent synchronized injection is executed according to data which is obtained after the complete response of an air flow meter so that the quantity of unsynchronized injection is found at a step 102. If NO at least one of the steps 96 and 98, the flow meter for the subsequent synchronized injection has only prematured response, on account of which at a step 94, the quantity of unsynchronized injection is tiwce as much as that obtained at a step 100.

IPC: B01D50/00
Filed: 1981-10-09
Abstract: PURPOSE:To remove dusts contg. oils virtually thoroughly by capturing the oils and other fine powder dusts respectively dividedly with good efficiency. CONSTITUTION:The oils in a liquid well 26 are sprinkled on a primary filter 7 like showers from nozzles 30 as shown by 31, and at the same time a fan 15 runs so that the oilmists are captured by the filter 7 and other fumes and  powder dusts are captured with a juxtaposed secondary filter 16. These oils and dusts are recieved in the liq. well 26 and a dust collecting case 29, respectively, and since these are provided separately by means of a partition plate 6, the flow of the fumes, etc. from the chamber B to the chamber A is prevented. If a cover body 25 is not provided, the positions of the plate 6 and a guide plate 27 are important. Since the fumes on the chamber B side do not enter the well 26, the fumes contained in the oils are only those captured by the filter 7, thus the increase in the viscosity of the oils is suppressed over a long period of time and maintenance is improved.
